Study on Microstructure and Properties of New Martensitic Wear-resistant Steel
1. Chemistry components
New martensitic wear-resistant steel generally contains C, Cr, Mn, Ni, Mo, W, V, Ti and other alloying elements. It has good wear resistance and plasticity due to its high carbon content, high hardness and impact toughness due to high alloying elements such as chromium and molybdenum, and a certain degree of corrosion resistance due to added nickel, molybdenum, copper, and other alloy content.
2. Microstructure
The microstructure of new martensitic wear-resistant steel mainly consists of martensite, bainite, and pearlite. Among them, martensite is the primary structure of new martensitic wear-resistant steel, which has a high hardness and good wear performance. The composition of bainite and pearlite increases the strength and toughness of the steel, and disperses the martensite, so as to reduce the brittleness of the material.
3. Performance
New martensitic wear-resistant steel has excellent wear resistance, hardness and good toughness, which is suitable for use in harsh working conditions such as pressure, impact, and abrasive environment. In addition, it also has good resistance to high temperature, oxidization, and impact fatigue under alternating low temperature and high temperature.
In conclusion, new martensitic wear-resistant steel has excellent wear resistance, hardness, and toughness, and is suitable for working in harsh working conditions. It has great potential in application. With the development of technology, new martensitic wear-resistant steel will bring revolutionary changes to the metal materials industry.
